Constructor & Destructor Documentation

GLDepthTexture()

GLDepthTexture::GLDepthTexture ( GLint magFilter = GL_LINEAR, GLint minFilter = GL_LINEAR, GLint wrapX = GL_CLAMP_TO_EDGE, GLint wrapY = GL_CLAMP_TO_EDGE )

inline

Create a depth texture with initial sampler parameters.

Parameters

magFilter	Magnification filter (e.g., GL_LINEAR).
minFilter	Minification filter (e.g., GL_LINEAR).
wrapX	Wrap mode for S (x) coordinate (e.g., GL_CLAMP_TO_EDGE).
wrapY	Wrap mode for T (y) coordinate (e.g., GL_CLAMP_TO_EDGE).

Postcondition

A texture name is generated, parameters are applied, and depth comparison is enabled (GL_COMPARE_REF_TO_TEXTURE with GL_LESS).

~GLDepthTexture()

GLDepthTexture::~GLDepthTexture ( )

inline

Destroy and delete the GL texture name.

Member Function Documentation

getHeight()

uint32_t GLDepthTexture::getHeight ( ) const

inline

Face height in texels.

Here is the caller graph for this function:

getId()

const GLuint GLDepthTexture::getId ( ) const

inline

Retrieve the OpenGL texture object name.

Returns

GLuint of the managed depth texture.

Here is the caller graph for this function:

getType()

GLDepthDataType GLDepthTexture::getType ( ) const

inline

Depth storage type used for allocation.

getWidth()

uint32_t GLDepthTexture::getWidth ( ) const

inline

Face width in texels.

Here is the caller graph for this function:

setEmpty()

void GLDepthTexture::setEmpty ( uint32_t width, uint32_t height, GLDepthDataType dataType = GLDepthDataType::DEPTH24 )

inline

Allocate empty depth storage of the requested size/format.

Parameters

width	Width in texels.
height	Height in texels.
dataType	Depth format to allocate (DEPTH16/DEPTH24/DEPTH32).

Postcondition

Internal storage is defined at level 0; pixel store alignment is set to 1 for pack/unpack.

setFilter()

void GLDepthTexture::setFilter ( GLint magFilter, GLint minFilter )

inline

Update the filtering parameters on the bound texture.

Parameters

magFilter	Magnification filter.
minFilter	Minification filter.
